Machining and grinding
Machining oils provide lubrication and cooling during metal machining operations such as turning, milling, drilling and grinding. They reduce friction between the cutting tool and workpiece, dissipate heat generated during machining and help extend tool life. They also contribute to achieving the required surface finish and dimensional accuracy of machined components. Depending on their formulation and application, metalworking fluids are divided into water-miscible cooling and lubricating fluids and cutting oils.
Choose a metalworking fluid based on the material being machined, the complexity of the operation and the required cooling and lubricating performance. We offer FUCHS ECOCOOL and TARFIL metalworking fluids for various machining applications, including products suitable for standard and medium-duty operations.
Metalworking Fluids by Application
| Application | Recommended Fluid | Key Characteristics |
|---|---|---|
| General machining and cooling | ECOCOOL MK 3 | Mineral oil-based, water-miscible fluid that forms a stable emulsion |
| Medium-duty machining of cast iron and metals | ECOCOOL 68 CF 3 | Semisynthetic cutting and cooling fluid for cast iron, steel, aluminium and non-ferrous metals |
| Demanding machining operations | TARFIL AT | Chlorine-free cutting fluid and metalworking lubricant |
| Lubrication and cooling during drilling and other operations | DEBBEX Cutting and Drilling Oil Spray | Spray lubricant for easy application to the tool and machining area |
Water-Miscible Metalworking Fluids
Water-miscible metalworking fluids combine the cooling properties of water with the lubricating performance of oil-based components and other additives. When mixed with water, they form an emulsion or stable working fluid that dissipates heat, reduces friction and helps protect both workpieces and cutting tools.
FUCHS ECOCOOL MK 3 is a mineral oil-based cutting and cooling fluid designed for machining under normal operating conditions. When mixed with water, it forms a stable emulsion. FUCHS ECOCOOL 68 CF 3 is a semisynthetic fluid designed for medium-duty machining of cast iron, steel, aluminium and non-ferrous metals.
Cutting Fluids for Demanding Machining Operations
When machining operations place higher demands on tool lubrication and friction reduction, choosing the right cutting fluid is essential. FUCHS TARFIL AT is a cutting fluid and metalworking lubricant designed for demanding operations. It is chlorine-free.
For drilling and other operations requiring easy and precise lubricant application, DEBBEX Cutting and Drilling Oil Spray is also a suitable option. It helps reduce friction and tool wear.

Frequently Asked Questions
What are metalworking fluids used for?
Metalworking fluids cool and lubricate the contact area between the cutting tool and workpiece. They reduce friction and tool wear, dissipate heat and help achieve a high-quality machined surface finish.
Which metalworking fluid should I use for steel and aluminium?
FUCHS ECOCOOL 68 CF 3, a semisynthetic metalworking fluid, is suitable for medium-duty machining of steel, aluminium, cast iron and non-ferrous metals. The final selection should always be based on the specific material and machining operation.
What is the difference between a metalworking emulsion and cutting oil?
A metalworking emulsion is produced by mixing a water-miscible fluid with water. It provides effective cooling while also ensuring lubrication. Cutting oil is used without dilution with water and places greater emphasis on lubricating the cutting tool and workpiece. The appropriate type depends on the machining process and its specific requirements.
How do you properly prepare a metalworking emulsion?
Prepare water-miscible metalworking fluids according to the manufacturer's recommendations and at the specified concentration. In general, the concentrate should be added to water while stirring, not the other way around. The concentration should be checked regularly using a refractometer.
